Essentials EC Meter

Hydroponic EC Meter 

EC Meters are an essential part of a grow room environment.

When building up the plant’s internal EC and subsequently that of the substrate, it is important to take into account the demands of the plant’s growth. This demand is controlled by assimilation. The bigger a plant grows, the more nutrition it will need. These nutrients are partly locked up in the plant and converted into amino acids, oils, fats etc., but some nutrient salts also remain in the plant’s sap and these determine the plant’s internal EC. Potassium is one of the most important nutritional elements for this.

Once the plant has finished the vegetative growth phase, it can still absorb a lot of potassium for its internal osmotic value and the ovaries. The ovaries are not the fertilised 'seed'. However, this increasing rate of uptake comes to an end. After approximately 60% of the cultivation cycle, the plant will have taken up enough nutrients from the stock in the substrate. The game of nutrient stock versus applied EC now starts for growers.

The ESSENTIALS EC Meters are reliable and hold up to 10 past readings. This means growers are able to easily keep track of their EC readings, allowing for quick reactions to any abnormal readings.

Key USPs:

• Memory function for 10 readings allowing for readings to be tracked easily
• Water Resistant
• Shock Resistant
• Low Battery Alert
• Simple calibration using VitaLink Essentials Calibration Fluid

Features and Benefits

• Memory Function - This allows a grower to check and log changes in the EC levels and correlate changes to potential alterations that may be taking place
• Water resistant - If the meter is accidently dropped in a solution, it will float and not break if taken out of the liquid immediately and dried quickly
• Shock resistant - Shock resistance allows for accidental dropping of the instrument without breaking
• Low Battery Alert - Gives a warning when there is 2 hours running time left, so you can change the battery in good time
• Energy saving shut-off - Turns off the meter when it is not in use
• Simple Calibration using VitaLink Essentials Calibration Fluid - Some meters can be complicated to calibrate. Simply dip the probe in the solution and press the CAL button until CAL appears onscreen.

Science Behind the Product
pH meters work by taking readings of the pH levels of a solution. They are equipped with sensors, which when immersed in a liquid give the reading of what levels the solution is at. It is pivotal to regularly calibrate the machine/sensors as it is a scientific piece of equipment which requires simple maintenance.
